We previously had 4 ducks, two male, two female. The two females were the original but were introduced to the duckling males when the boys were a few weeks old. They get on fine. We incubated one of the subsequent produced eggs and now have a fifth duck - gender unknown. For the first couple of months we have brought him up with the chickens who were born at the same time as him. However we now feel it is time to make him live with his own kind. He's a couple of months old and looks adolescent / adult, but is still very young. However whenever we drop him round back the other 4 go for him viciously, particularly the Aylesbury who is oddly enough his own mother. We've tried a few intros now, usually each for roughly half an hour, however every time they chase him to the other side of their run. Is there anyway to get him accepted into their flock. The other 4 all get on fine, however they don't seem to like the idea of a 5th. If we leave them to it will they eventually sort out their differences? Just how realistic are my fears of them drowning him in the bath? What can we do to help them get along? Is it just a lost cause and is our duck forever destined to be a odd looking chicken? Advice desired. Thanks.
